What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)

    An adverse events is defined as the appearance of (or worsening of any pre-existing) undesirable signs, symptoms, or medical conditions that occur after participant's signed informed consent has been obtained. A SAE is described as any adverse event that leads to death, is life threatening, causes or prolongs hospitalization, results in a congenital anomaly, or any other important medical event not described above.

    Measured: Up to 2.8 years

  2. Percentage of Participants With Dose Limiting Toxicities (DLTs)

    Percentage of participants with dose limiting toxicity were reported.

    Measured: Up to 2.8 years

  3. Percentage of Participants With at Least One Dose Reduction

    Percentage of participants with at least one dose reduction were reported.

    Measured: Up to 2.8 years

  4. Percentage of Participants With at Least One Dose Interruptions

    Percentage of participants with at least dose interruptions were reported.

    Measured: Up to 2.8 years

  5. Dose Intensity Received by Participants

    Dose intensity of LTT462 received by treatment group was reported.

    Measured: Up to 2.8 years

Secondary outcomes (12)

    Measured: Every 2 cycles after starting LTT462 treatment until end of treatment (Up to 2.8 years)

  2. Percentage of Participants With Disease Control Rate (DCR)

    Percentage of participants with disease control rate were reported.

    Measured: Every 2 cycles after starting LTT462 treatment until end of treatment (Up to 2.8 years)

  3. Duration of Response (DOR)

    DOR is defined as the time between the date of the first documented response (complete response [CR] or partial response [PR]) and the date of progression.

    Measured: Every 2 cycles after starting LTT462 treatment until end of treatment (Up to 2.8 years)

  4. Progression Free Survival (PFS)

  5. Overall Survival (OS) - Only for Dose Expansion Phase

    Median time for overall survival, only for dose expansion phase was reported.

    Measured: Every 2 cycles after starting LTT462 treatment until end of treatment (Up to 2.8 years)

  6. The Maximum (Peak) Observed Plasma, Blood, Serum, or Other Body Fluid Drug Concentration (Cmax) After Single Dose Administration of LTT462

    Cmax is the maximum (peak) observed plasma, blood, serum, or other body fluid drug concentration after single dose administration expressed in mass x volume-1.

    Measured: day 1, day 15

  7. Area Under the Curve From Time Zero to the Last Measurable Concentration Sampling Time (AUClast) of LTT462

    AUClast is the area under the curve from time zero to the last measurable concentration sampling time calculated by mass * time *volume^-1

    Measured: Cycle 1 Days 1, 2, 3, 8, 15 and 16; Cycle 2 day 1 and 15; Cycle 3 Day 1; Cycle 5 Day 1

  8. The Time to Reach Maximum (Peak) Plasma, Blood, Serum, or Other Body Fluid Drug Concentration (Tmax) After Single Dose Administration of LTT462

    Tmax is the time to reach maximum (peak) plasma, blood, serum, or other body fluid drug concentration after single dose administration.

    Measured: day 1, day 15

  9. Elimination Half-life (T1/2) of LTT462

    T1/2 is the Elimination half-life.

    Measured: Cycle 1 Days 1, 2, 3, 8, 15 and 16; Cycle 2 day 1 and 15; Cycle 3 Day 1; Cycle 5 Day 1

  10. The Area Under the Curve Calculated to the End of a Dosing Interval (Tau) at Steady-state (AUCtau) of LTT462

    AUCtau is the area under the curve calculated to the end of a dosing interval (tau) at steady-state calculated by formula amount *time * volume^-1

    Measured: Cycle 1 Days 1, 2, 3, 8, 15 and 16; Cycle 2 day 1 and 15; Cycle 3 Day 1; Cycle 5 Day 1

  11. Accumulation Ratio (Racc) of LTT462

    Racc is the accumulation ratio calculated by AUCtau ratio Day 15 versus Day 1.

    Measured: Cycle 1 Days 1, 2, 3, 8, 15 and 16; Cycle 2 day 1 and 15; Cycle 3 Day 1; Cycle 5 Day 1

  12. Changes From Baseline in Relative Quantity (RQ) of Dual Specificity Phosphatase 6 (DUSP6) in Tumor Tissue and in Blood

    Assessment of Pharmacodynamic (PD) effects of LTT462 in tumor, pre- and post- treatment tumor biopsies were examined for expression of DUSP6. For assessment of PD effects in blood, levels of DUSP6 were measured in blood samples.

    Measured: Cycle 1 Days 1, 2, 3, 15 and 16

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing LTT462 in people with Ovarian Neoplasms and Non-Small-Cell Lung Carcinoma, run by Novartis Pharmaceuticals at 7 sites in 6 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 19 Sep 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites in United States, Germany, Japan, Singapore, Spain and 1 more country. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 19 Sep 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs) (time frame: Up to 2.8 years). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Sep 2019; AzTrials last refreshed its copy on 6 Nov 2026.
